ARCTIC: An IoT-Based System for Child Tracking in Day Care

TARGET GROUP: CHILDREN

OBJECTIVES

·        To develop an IoT-based system for child tracking.

SUMMARY

How beacons can be used in building a less expensive user tracking application. Let us assume the scenario where 3 staff members are accompanying 15 children on a field trip, where every staff is responsible for five children each. Each child is provided with a Bluetooth BLE beacon in the form of ID tags. The proposed system is in form of an Android application and is installed in the staff mobile phones. When the Bluetooth BLE beacons are turned ON, the android application scans the beacons and displays them on the home page of the application. The staff responsible for the children will be able to see the child and the distance of the child from the device. The staff will also be able to set the maximum safe distance. In case a child leaves the set maximum distance, the staff will be alerted via a notification that the child has crossed the set distance. To find the relative location of the child, trilateration is implemented. The distance of each child is stored in the database as the distance from all the three staffs. When a child crosses the maximum set distance, the location of the child is calculated using the trilateration algorithm and a notification is sent to the staff closer to the child and the location is displayed with a Map activity.
